19 Claims.

This invention relates to folding tables, and especially card or game tables of the type having folding legs to be maintained both in extended and folded position, and wherein as disclosed and claimed in my copending application Serial No. 74,237, filed April 14, 1936, and issued as Patent No. 2,077,701, April 20, 1937, spring-urged pairs of toggle links are provided for holding the legs in said positions, and operating connections, including links extending substantially diagonally of the table top, are provided for conjoint positioning of all the legs.

An object of the present invention is to provide improved operating connections for effecting positioning of all the legs of the table through the manual operation of any one of the legs, and for providing improved connections such that when the legs are locked in extended position all mayv be released to be folded by the release of any one.

'Another object is to provide a releasing means as last referred to of such type that not only can a manually operated release actuator be operated at any one of the four corners of the table selected at random, but such release can be effected with considerable ease and with a natural movement by moving said actuator toward rather than away from or parallel to the marginal portion of the table top. These improved release actuators are located near the margin of the tabletop, each to be. grasped by hand together with the table frame, so that the actuatorV may be operated easily by simply urging it toward the frame Aby a squeezing movement similar to that employed when closing a pair of pliers, this movement being familiar to most people and being simple and effective. A feature of the improved releasing means of the present invention, as just described,

is the provision of a leverage system whereby use is made of the lever principle in reducing the operating force required and increasing the extent of travel of the part to bel moved so that only a small hand pressure is necessary, operating through a relatively large travel or stroke, to unlock the legs of the table when the latter are in extended position.

Still another object is to provide operating connections between the legs wherein a single substantially diagonally extended link can serve each leg, and in that connection to provide a central structure at the underside of the table top to assist in mounting such links while at the same time strengthening a thin table top and permitf ting economies of material and time ,in fabricating the table.

Other features and advantages will hereinafter appear.

In the accompanying drawings:

Figure 1 is a bottom plan view of a table made in accordance with this invention, with the legs in folded position.

- Fig. 2 is a fragmentary detail bottom plan of one corner of the table, with the shown leg folded in under the bottom of the table top.

Fig. 3 is a fragmentary view of one corner of the table in vertical section on line 3-3 of Fig. 2, With the table upside down, and showing the leg of Fig. 2 folded down or collapsed.

Fig. 4 is a view similar to Fig. 3, but showing the leg extended, this view being taken on line 4-4 of Fig. 5.

Fig. 5 is a view similar to Fig. 2, but showing the leg of the last-mentioned view extended, and in section.

Fig. 6 is a fragmentary detail View, being substantially a vertical section, taken on the line 6 6 of Fig. 1.

As an exemplifying embodiment of the present invention is shown in the accompanying drawings, the invention is applied to a card table of the rectangular-top type wherein four legs lil respectively fold or collapse to lie within and substantially to parallel one of the four straight wall elements of a marginal frame I I on the underside of a table top I2.

Each leg IB is secured to a plate` `I3 having a barrel I4 receiving a pin I5 carried by a bracket I6. Each bracket I6 is shown as fastened by screws in the corner formed by a pair of meeting sides of the frame I I.

The legs I 0 are moved from the folded position shown in Figs. 2 and 3 to extended position as shown `in Figs. 4 and 5 by an actuating mechanism including for each leg a pair of toggle links I'I and I8 hinged together at I3. The links are connected respectively to the legs and the table by pins 20 and 2|, and are positioned so as to lock the legs when in extended position, and each link I8 has an arcuate slot 22 in which rides a pin 23 carried by the bracket I6, so that the movement of the link is limited thereby.

Each toggle link I8 is connected to la spring 24 having its other end shaped to form a loop which bears against an accommodatingly shaped concave cut-out in the bracket I6, this end of the spring being held by a pin 25 attached to the marginal frame II. The spring 2 4 acts to urge the links I'I and I8 to either folded or extended straight positions, depending on Whether the moving end of the spring lies'above or below the pin 2|. Thus the spring may urge the leg into either extended or folded position from a dead center position intermediate these positions (refer to Figs. 3 and 4).

There is disclosed in my Patent No. 2,005,716 a means for operatively connecting all four legs, and the p-resent invention is concerned in` part with an improved form of said means.

As here shown, the means last referred to comprises four substantially radially extended single links 26 formed for lightness andstrength` of channel metal strips and flatted to spatulate form at opposite ends. lThe inner end of each of these links is pivotally connected, as indicated at 26a, to the outer end of one of the four arms of a cruciform rocker plate 26', itself pivoted at 26, at the center of the table top. The outer end of each of said links is pivotally connected, as

indicated at 26D, to one of four like shaped plates, constituting actuating `levers 21, kone for each of the legs Il). i

Each of these actuating levers 21 isv pivotally mounted by a pin 28 set in the` appropriate bracket plate I6.'

The rocker plate 2t"y is mounted atop a padstructure 29 at the center of the table top of comparatively small yet adequate area. As shown, said pad-structure comprises a wood block 29 and an overlying metal wear plate 23". The tcp vof pad-structure 29 is here shown at such distance below the underside of the table top I2, relative to the preferably somewhat higher locations of the levers`21 that the links 26, of channel form as aforesaid, and desirably of lightweight sheet metal, are slightly sprung or tensioned in toward the table top as they approach their connectionswith thelevers 21. Such al treatment of these links is-now favored, as apparently tending to rigidify the general operating assembly and give an improved action. Also, the wood block 29 stiiens that part of the table top l2 which, when the table top is of extreme thinness and light material, might otherwise betray after some use a tendency toward buckling or other distortion. Furthermore, as shown in Figs. 1 and 6, said wood block, which can be glued to the table top, provides an entering material for ordinary woodscrews,'so that such screws, as indicated at 29a, can mount the wear plate 29. The heads of these screws are cleared by the rocker plate 29 by virtne of the latter being upwardly centrally dished as shown in Fig. 6; and such dishing in turn serving as a convenient housing for the riveted end of the pivot 26 for said rocker plate.

Each of levers 21 has an apertured arm Sti and an extension 3| having an upturned arcuate flange 32 with the center of curvature of such arc in the axis of pin 28. According to the invention, the arm 30 is longer than the extension arm 3|, and preferably the longer arm is approximately twice the length of the shorter arm. I have found that by so constructing the lever 21 operation of the legs of the table is made much easier and more positive. The extension 3| is provided with a recess 33 which opens into a slot 34 dividing the flange in twoparts, and a pin 35 carried by the toggle I3 engages said slot so as to form a gear-connectionbetween the toggle and the lever 21. In effect, the lever 21 acts as a two-tooth contrate Wheel, and the toggle I8 and pin 35 as a one-tooth pinion, each engaging the other to coordinate the movements of the lever and link. It will be seen that with the legs and links l1 and I8 folded, the lever 21 will be positioned as in Fig. 2, and with the leg and links extended the lever will be positioned as in Fig. 5.

The parts just described, then, provide a means whereby when any one leg is moved toward folded or extended posit-ion, all the other rlegs move simultaneously and correspondingly.`

According to the present invention, and with the parts last described omitted, the operating mechanism Vlocally coupled to and associated with any actuating lever 21 can be operated, so as to allow any leg I to be moved separately and individually from closed to open or extended condition, that is, to redispose the toggle links l1 and i8 of a leg from the set thereof wherein such leg is locked in extended condition (here the aligned-center setting of said links shown in full iines in Fig. 4), to a releasing condition (here that of said links as shown in broken iines in Fig. 4). When the toggle links of any leg are in the position last referred to, said leg, it will be understood, can be manually collapsed; while with the toggle linksarranged as in Figs. 3, as they are arranged when their leg is collapsed, such links can be manually extended Without any necessity for varying the setting of the toggle links, merely by pulling the free end of the leg away from the table top.

However, with all the legs connected for conjoint movement and positioning of all by any one, due to the inclusion of the links 26 and the cruci-form plate 26', aii the legs will be vsimultaneously extended from collapsed position when any one of them is'manually extended from that condition. Also, all the legs will be simultaneously collapsed from extended condition as any one of them is manually collapsed from extended position, provided the toggle links I1 and i8 associated with that leg are rst redisposed as last described, that is, changed from the full line condition of Fig. 4 to the broken line condition of that view.`

In order to provide for this, the present invention incorporates an auxiliary means, which here may called the toggle-breaking means; one of such means for each pair of toggle links i1 and I8. Each toggle-breaking means as here shown includes an arm 36 constituting a handle readily accessibly offset from one of the levers 21 and pivoted to the latter at 26h, that is, somewhat loose on the same pivot by which said lever 21 and link 26 are joined. Each handle 36, here shown of metal and of channel shape, and spatulate at its pivoted end as indicated at 3fm, has a side flange offset from its spatula as shown most clearly in Figs. 4 and 5, where such flange is marked 31.

This fia-nge is so carried by its handle 35 that while the handle can be swung relativeto the lever 21 as shown in full lines in Fig. 5, once it is swung back to extend beyond said lever as shown in Fig. 2 it cannot be swung further in the direction last mentioned, due to the flange 31 being brought against a straight edge constituting a stop on lever 21.

A xe'd reactance element 33 is provided for each handle 36, the same being shown as in the form of awood-screw with a half-round head.

When all the legs are collapsed as shown in Figs. 1, 2, and 3, all the four handles 36 are considerably spaced from the marginal frame II below the table top. Then, furthermore, the spring 2Q associated with each pair of toggle links l1 and I8, is'only resiliently maintaining these links collapsed, and hence the legs, now collapsed, are

only resiliently .so maintained; as aforesaid; all the legs can be moved'from collapsed or foldedfc'ondition toextended condition, on manually pulling.- any one leg away from the table top.

However, when the legs are extended', the springs 24 are holding the toggle links I1 and I3 in aligned-center settings as' shown in Fig. 4, and' hence said toggles are lockedtohold the legs locked in extended condition. Then each handle 36A is disposed as shown by full lines in Fig. 5,

, being forced to that position by the adjacent reactance element 38. In order to break the lock of' any pair of toggle linksv l1 and I8', that is, to throw the pivot between two links out of line with the two other. link pivots, and so release the associated leg for full movement toward collapsed or folded condition, it is merely necessary manually to engage the free end of the associated handlei36 and the frame ll of the table, such end now Well away from said frame,v and force said handle in toward said frame and in a direction parallel to the table top by a natural squeezing movement, as employed in operating a pair of pliers. During this operation, the reactance element bears against the flange 31 of the handle and acts as a fixed fulcrum whereby the handle is rocked thereon as a lever o-f the lfirst class, thus throwing the lever 21 to the broken line position of Fig. 5 as the handle is moved from the'full line position there shown to the broken line position indicated at 36'. This sufficiently rocks said lever to cause a movement of the pin A35 great enough to break the lock of the associated pair of toggle links.

The length of the arm 30 of the lever 21, being greater than that of the arm 3|, is of particular importance here since it provides for breaking of the toggle links With only a very little force on the handle 36, since an advantage of leverage is obtained through the lever 21. Furthermore, it is preferable to locate the fulcrum 38 so that a similar advantage in leverage is obtained when operating the handle 36 to engage said fulcrum. Referring to Fig. 5, the portion of the handle 36 between the fulcrum and the pivoted end 36a is much shorter in length than the handle portion on the other side of the fulcrum. Therefore, by this syste-rn of levers 36 and 21 only a proportionately small pressure is required on the handle to operatethe toggles for breaking the legs.

As, incidental to this'release of said pair of toggle links, the associated leg Il) moves slightly away from extended position, the three other pair of to-ggle links are similarly released and the three other legs are similarly moved, due to the links 26 and the rocked plate 26'. Then any one of the legs can be manually forced to fully collapsed or folded position and with it the other three legs.

Variations and modifications may be made Within the scope of this invention, and portions of the improvements may be used without others.
